Wanting to start a new glider club

This is all cart before the horse stuff. To start a club the first thing you need to establish is a group of committed individuals with shared goals and sufficient funds and competences. Then, before expending effort and money, you need to thing long and hard about how you are going to train members and keep attracting more new members to cover the high drop out rate that seems endemic in gliding. Then the group needs to judge whether you are going to have the human and financial resources to cover all the other stuff involved in running a gliding operation - maintenance, regulatory, management etc. Then you need a site. Then you can decide on what hardware is most suitable.
